I find the Conquest's focus really excellent for this. And when I describe it as fast, I don't want to give the impression it is fast as a rocket, but neither do you have to pump the focus wheel like a mad thing to get from near to far and back again. And you are right to the extent I would expect to have less focusing to do over the middle range of distances which might well be covered by the depth of field plus a little help from my own accommodation.As for the overshooting, well, many years ago one of my early pairs of binoculars came with instructions to always overshoot your target slightly and then just back-track gently with the focus wheel to achieve perfect focus. I have done this ever since and can do this easily with the Conquest HD and never find myself going backwards and forwards hunting for, but never achieving, a sharp image. Of course what works for me might not work for everyone.LeeLee</blockquote>
